Definitions
- An adapter is a base component that is fixed to the digging edge of an excavator by welding, mechanical attachment or being cast as an integral portion of the bucket lip.
- the adapter itself may have multiple parts, particularly in larger sized teeth, but is commonly a single component.
- the adapter includes a forwardly projecting nose as a mount for the wear member.
- the point has a generally wedge-shaped configuration with top and bottom walls that converge to a digging edge.
- the base or rear end of the point includes a rearwardly opening socket by which the point is received over the adapter nose.
- the lock is inserted into a passage that is collectively defined by aligned openings in the adapter nose and the point.
- a pry relief 115 is formed on opposite sides of head 106. As seen in Figure 15 , the relief is a shallow depression bounded by a peripheral edge 117 except along one side 117a, which is open. The outer segment defines a pry edge 117b against which a pry tool engages the lock to pull the lock from the tooth.
- Head 106 is preferably formed to facilitate rotation of the locking member, prying of the lock, and installation and removal of a cap 133 adapted to plug hole 52 and inhibit the build up of fines around the lock during use.
- the head is formed with a hexagonal exterior (although other shapes could be used) to provide flats 134 for the engagement of a wrench (not shown).
- Chamfered surfaces 136 are provided adjacent two opposing flats 134 to enable the walls of the recess 135 in cap 133 to be received over the head to hold the cap in place ( Figs. 14 and 15 ).
- Resilient member 264 and retaining member 263 are bonded together by adhesive, being molded together, or other means.
- the ends 263c, 263d of retaining member 263 also help the body from turning when the locking member is rotated, in cooperation with the flat surfaces 264b, 264c of resilient member 264.
